I already have a custom dual exhaust that came on my truck when I bought it. It's not very loud though. How could I make it louder? It has to be legal though and I live in California

A new muffler and longtube headers can do that for ya

Well you wouldnt want a " muffler" cause the role of a muffler is to muffle the sound. Try a flowmaster outlaw.. no muffler there and its legal.

I don't want it obnoxiously loud just a little bit more than it is.

I'd go with a magnaflow than. Straight threw so you get good flow. but its got ceramic glass packing inside to give you a nice deep sound but not over bearing. Or you could go with a flowmaster super 44.. its louder than the magnaflow but its chambered so you won't get as good flow like your magnaflow
